Audited Supplier | Fine precipitated barium sulfate |
| Using barium sulfide and sodium sulfate solution refinement and impurity removal technology to obtain high-purity, whiteness precipitated barium sulfate; through professional crystal morphology control technology to obtain products with extremely narrow particle size distribution, giving it excellent dispersibility and processing performance; |
| The product has high purity, less impurities, and low conductivity; |
| The particle size distribution is narrow, and the average particle size (D50) is about 0.7-1.2μm; |
| Good gloss, excellent whiteness and weather resistance; |
| As a pigment filler, it can improve the dispersion performance of the pigment and increase the efficiency of the use of the pigment. This product is added 5-20% of titanium dioxide, the hiding power remains basically unchanged, and the gloss of the product can be greatly improved. |
